I have followed recommendations online and my file copy is working fine. But I am having a problem with is Flash Builder 4.7 running on VM 6.0.0 build-1295980. It is very, very slow.
Well, it's still not good.Copying large folders gives me around 1 MB/sec at the beginning, but then it goes down to 50-60 KB/sec or even less.
